The BB DE locomotives are multi-purpose locomotives, for line or yard traction in all gauges. Equipped with Diesel Electric transmissions, the BB DE locomotives with their two bogies whose axles are mechanically connected, combine efficiency and simplicity.
Presentation
Locomotive BB is part of CFD's DNA. The range of diesel electric locomotives extends from 680 to 2000 HP (500 to 1500 kW), in direct current traction or with a permanent magnet traction system, single speed or two speed ranges. There is bound to be the right locomotive for you.
The new generation BB locomotive, like all CFD rolling stock, is modular. From its frame base, the vehicle is adapted to the needs of the end user. It is thus possible to define the type of bogie, the axle load, to choose the size of the cab, the type of electric power train, the air production and of course the power of the diesel engine.

Diesel engine
The BB DE locomotive can be equipped with a CATERPILLAR or VOLVO diesel engine, for example, but solutions with other engine manufacturers are possible, with diesel or gas engines. The engines offered meet current environmental standards. For applications without environmental constraints, the engines are optimised for low fuel consumption. A Start and Stop system enables the engine to be stopped during long periods of idling and restarted automatically according to the pressure in the compressed air tanks. This system limits fuel consumption and extends the maintenance intervals. For greater power, twin-engine solutions can be used to ensure redundant power generation and reduce maintenance costs by using only one engine most of the time.
Traction system
This locomotive is already available with two different traction systems to meet all our customers' requirements. The two powerful traction systems are integrated into the same interfaces on the locomotive frame, reducing design costs and production times. All that remains to be done is to choose the type of transmission when ordering: the choice is between the robustness and simplicity of the DC transmission with the CFD D33 dual motor or the efficiency and control flexibility of the permanent magnet solution. CFD is attuned to new technologies and can offer you hybrid solutions (with or without current collection on catenary on electrified tracks) or 100% batteries, always in line with your needs.

DC Traction
The DC drive train is based on two robust D33 double DC motors designed by CFD and located between the bogies. This solution, which has been widely tested in rail transport, is extremely simple and allows exceptional tractive effort. The simplicity of the components, their robustness and ease of maintenance make this solution ideal for operations in harsh environments or isolated areas.
SRPM Traction
The SRPM drive train, equipped with permanent magnet motors and generators, is built around a DC bus. This solution is characterized by the use of power electronics components of remarkable compactness thanks to liquid cooling.
The exceptional performance of these components and the absence of heavy maintenance significantly reduces operating costs.
Driver's cab
The driver's cab has been developed to be mounted on either TRIAX or BB locomotives with a design that offers excellent visibility from the driver's cab. It is equipped with diesel air conditioning and heating to warm up the diesel engine before starting it in cold weather. The side windows are based on an innovative concept allowing them to slide into the cab roof. The unobstructed opening allows the operator to have a wide view outside the cab and around the machine. A classic solution with sliding half windows is also available.
